1.2.1 Spa/Hot Tub Safety Rules
WARNING
The following “Safety Rules for Hot Tubs,”
recommended by the U.S. Consumer Product
Safety Commission, should be observed when
using the spa.
AVERTISSEMENT
Les Règlements suivants pour Cuves
Thermales, tel que recommandés par la
Commission U.S. de Sécurité des Produits
pour les Consommateurs, devraient être
respectés lors de l’utilisation du spa.
Page 1
WARNING
The U.S. Consumer Product Safety
Commission warns that elevated water
temperature can be hazardous. Consult heater
operation and installation instructions for water
temperature guidelines before setting
temperature.
AVERTISSEMENT
La U.S. Consumer Product Safety Commission
indique que des températures de l’eau élevées
peuvent être dangereuses. Voir la notice
d’installation et de fonctionnement pour le
réglage de la température.
1.
Spa or hot tube water temperature should never
exceed 104°F (40°C). One hundred degrees
Fahrenheit (100°F [38°C]) is considered safe for
a healthy adult. Special caution is recommended
for young children.
2.
The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and
subsequently result in drowning.
3.
Pregnant women take note! Soaking in water
above 102°F (38.5°C) can cause fetal damage
during the first three months of pregnancy
(which could result in the birth of a braindamaged or deformed child). If pregnant women
are going to use a spa or hot tub, they should
make sure the water temperature is below 100°F
(38°C) maximum.
4.
The water temperature should always be checked
with an accurate thermometer before entering a
spa or hot tub. Temperature controls may vary by
as much as 4F° (2C°).
5.
Persons with a medical history of heart disease,
diabetes, circulatory or blood pressure problems
should consult their physician before using a hot
tub or spa.
6.
Persons taking any medication which induces
drowsiness (e.g., tranquilizers, antihistamines, or
anticoagulants) should not use spas or hot tubs.
7.
Prolonged immersion in hot water can induce
hyperthermia.
Hyperthermia occurs when the internal body
temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and
Page 2
an increase in the internal body temperature. The
effects of hyperthermia include:
•
Lack of awareness of impending hazard
•
Failure to perceive heat
•
Failure to recognize need to leave spa
•
Physical inability to leave spa
•
Fetal damage in pregnant women
•
Unconsciousness resulting in a danger of drowning
1.2.2 Swimming Pool Energy Saving Tips
Water Pik Technologies offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without
sacrificing comfort.
1.
The American Red Cross recommends a maximum water temperature of 78°F (25°C). Use an
accurate pool thermometer. A difference of 4F°
(2C°) , between 78°F and 82°F (26°C and 28°C),
will use as much as 40% more gas.
2.
Carefully monitor the water temperature of your
pool in the summertime. You can reduce heater
usage due to warmer air temperatures.
3.
Find the proper setting on the pool heater temperature control and use the TEMP-LOK to
discourage further adjustments.
4.
Set the filter time clock to start the pump no
earlier than 6:00 AM during the pool heating
season. This is the time when nightly heat loss
balances.
5.
6.
If the pool is only going to be used on weekends,
reduce the heater temperature control setting by
8 or 10 degrees during the week. Reset it to the
desired temperature level a day or so before you
plan to use the pool.
During the winter or when on vacation for longer
than a week, shut down the heater by following
the shutdown instructions found on the inside of
the heater.
7.
Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other landscaping, cabanas, or fencing.
8.
Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on filter systems.
1.3 Warranty
The Lite2 heater is sold with a limited factory
warranty. Details are specified on the back cover of
this manual.
Make all warranty claims to an authorized Jandy
representative or directly to the factory. Claims must
include the heater serial number and model (this
information can be found on the rating plate), installation date, and name of the installer. Shipping costs are
not included in the warranty coverage.
The warranty does not cover damage caused by
improper assembly, installation, operation or field
modification. Also, damage to the heat exchanger by
corrosive water, is NOT covered by the warranty. See
Section 8.1 for maintaining proper pool water chemistry.
NOTE: Keep this manual in a safe place for
future reference when inspecting or servicing
the heater.
1.4 Codes and Standards
The Lite2 pool and spa heater is design certified
by CSA (Canadian Standards Association) as complying with the latest edition of the “Standard for Gas
Fired Pool Heaters”, ANSI Z21.56 in the USA and
CSA-4.7 in Canada.

Figure 1. General Configuration.
The Lite2 LG heater may be installed indoors or
outdoors as outlined in later sections. Location of the
heater below or above the pool water level affects
operation of its water pressure switch. See sections
on water piping and heater start-up for more information about this.
Avoid placing the heater in locations where it can
cause damage by water or condensate leakage. If this
is not possible, provide a suitable drain pan to catch
and divert any leakage. The pan must not block natural
flow of air around the heater.
All criteria given in the following sections reflect
minimum clearances as stated in the national standards. However, each installation must also be evaluated taking into account the prevailing local conditions
such as wind speed and direction, proximity and
height of walls that may block ventilation or cause
down drafts, and proximity to public access areas.
2.3.2 Clearances
The heater must be placed to provide clearances
on all sides for maintenance and inspection. There
must also be minimum distances maintained from
combustible surfaces (see Table 2).
At least 20" (500mm) access must be available in
front of the heater for burner removal.
If the heater is to be installed in a garage, or
similar structure, all burners and burner ignition
devices must have a minimum 18" (457mm) clearance
above the floor.

2.3.3 Flooring
The heater shall be installed on a level floor of
noncombustible construction or on fire-resistant slabs
or arches. Noncombustible flooring is defined as
flooring material and surface finish not capable of
being ignited and burning and with no combustible
materials against the underside. Acceptable materials
are those consisting entirely of a combination of steel,
iron, brick, tile, concrete, slate, glass or plaster. Do not
install the heater directly on a combustible wood or
carpet floor without placing a noncombustible platform
between the floor and the heater.
The heater can be installed on a combustible
floor if a noncombustible base assembly, available
from Jandy, is used. See the heater rating plate or the
Parts List (Section 11) of this manual for the appropriate base part number. Heaters must never be
installed directly on carpeting.
As an alternative to the Jandy noncombustible
base plate, in the United States, the National Fuel Gas
Code allows a heater to be placed on a combustible
surface when there is a platform under the heater
made of hollow masonry no less than 4 inches (102
millimeters [mm]) thick, covered with sheet metal at
least 24 gauge thick and extending beyond the full
width and depth of the heater by at least 6 inches (152
mm) in all directions. The masonry must be laid with
ends unsealed, and joints matched to provide free
circulation of air from side to side through the masonry
(see Figure 2). If the heater is installed in a carpeted
alcove, the entire floor of the alcove must be covered
by a noncombustible panel.
2.3.4. Outdoor Installation
Lite2 heaters can be installed in the low-profile
top configuration as received from the factory, or with
an optional high wind vent cap.
Locate the heater in an open, unroofed area.
Do not install the heater under a deck.
OPEN
Note: Clearances listed in Table 2 are
manufacturer's tested values. These are
given as minimum values. Where local
and national codes apply, and values
are different than those listed in Table
2, use the greater value to ensure safe
operation.
* Refers to side opposite piping
** A closet with no door
(In US-18 in (46 cm) clearance;
In Canada-24 in (61 cm) clearance)
Notes:
1. Blocks must provide solid base and be braced so they
cannot slip out of place.
2. Air openings in blocks must be arranged to provide
unrestricted opening through entire width or length of
base.
Figure 2. Non-Combustible Platform.
Do not locate the heater below or adjacent to any
doors, glass openings, louvers, grills, etc., which
connect in any way with an inhabited area of a building, even though the access might be through another
structure (e.g., a garage or utility room). In the United
States there must be a minimum of four (4) feet (1.22
m) horizontally or four (4) feet (1.22 m) vertically
between the heater exhaust point and any door, glass
opening, or gravity inlet to a building. In Canada, the
heater must be installed so that the exhaust point of the
heater is at least ten (10) feet (3.0 m) from any
building opening (see Figure 3).
Page 7
WARNING
United States
Do not install the heater with the top of the vent
assembly within 4 feet (1.22 m) horizontally and
4 feet (1.22 m) vertically of any opening into a
building.
Canada
Do not install the heater with the top of the vent
assembly within 10 feet (3.05 m) of any

assurez-vous que l’ouverture d’aération se
trouve à un minimum de 10 pieds (3,05 m) de
toute ouverture d’un bâtiment.
Figure 3. Outdoor Heater Installation.
The top surface of the heater must be at least
three(3) feet above any forced air inlet, or intake ducts
located within ten(10) feet horizontally.
If the heater is installed under an overhang, there
must be a minimum clearance of 5 feet (1.5 m) above
the top of the heater and the structure should not
overhang the heater more than 12 inches (0.30 m). The
area under the overhang must be open on three sides.
This prevents combustion gases from being diverted
into living areas through doors, windows, or gravity
inlets.
Ne pas installer ce chauffe-piscine sous une
saillie mesurant moins de 5 pi de hauteur. La partie
sous la saillie doit être ouverte sur 3 côtés.
If the heater is installed close to a structure,
protect it from rain water runoff with rain gutters on
the roof or other measures. Do not locate the heater
near irrigation sprinkler systems that could spray water
on it. Water from sprinklers may cause damage to
controls and electronic components.
Avoid locations where wind deflection off nearby
structures might cause downdraft conditions. Where
downdraft conditions exist, locate the heater at least 3
feet (0.91 m) from vertical surfaces (e.g., nearby
buildings and walls). The addition of a vent cap may be
necessary.
In Florida it is required that the heater be securely fastened to the equipment pad. Use a size
1/4" x 1-1/2" long stainless steel Tapcon® type concrete screws and washers at each of the four tabs
located at the base of the heater. Mounting the
appliance in this manner meets the applicable requirements of the Florida Building Code.
Mounting screws are not provided with this
heater. After placing the heater on the equipment pad,
drill a hole in the concrete at each of the four tabs on
the feet of the heater. (The correct size drill bit is
usually provided with the concrete screws when
purchased). Place a screw in each of the holes and
fasten the heater to the equipment pad (see Figure 4).
Do not over torque the screws.

2.3.5. Indoor and Outdoor Shelter
Installations
An outdoor shelter (Canada only) is an unoccupied enclosure which does not communicate directly
with occupied areas. All indoor installations and
outdoor shelter installations require the addition of a
factory approved drafthood. The drafthood must be
installed without modification and in accordance with
all local, state, provincial and national codes.
Une remise extérieure (au Canada seulement)
est un endroit inoccupé qui ne communique pas
directement avec les endroits occupés. Toutes les
installations intérieures et remises extérieures exigent
l’addition d’une coupe-tirage intérieur approuvée par
le manufacturier. La coupe-tirage intérieur doit être
installée sans aucune modification et selon les
exigences fournies par le manufacturier.
These codes, standards and Water Pik Technologies require that the heater be properly vented as
outlined in this manual. Proper ventilation of exhaust
and combustion air are essential for the safe and
Page 8
Notes:
1. An Underwriters' Laboratories or equivalent Nationally Recognized Testing Laboratory listed vent cap is required to
prevent downdraft and allow the heater to function properly and safely.

SECTION 3.
Venting
3.1. Combustion Air Supply
The heater location must provide sufficient air
supply for proper combustion and ventilation of the
surrounding area as outlined in the latest edition of
ANSI standard Z223.1 or in Canada, CAN/CSAB149.1, and any local codes that may be applicable.
In general, these requirements specify that the
room in which a heater is installed should be provided
with two permanent air supply openings; one within 12
inches (305mm) of the ceiling, the other within 12
inches (305mm) of the floor. All indoor installations
must have openings to outside air for combustion,
ventilation, and dilution of flue gases from inside the
building (see Figure 5 and Table 3). Water Pik Technologies does not recommend indoor installations that
do not provide combustion air from outside the building.
All outdoor shelter installations (Canada only)
must have uninterrupted openings to outside air for
combustion and ventilation. The installation must be in
accordance with the latest edition of CAN/CSAB149.1. Water Pik Technologies does not recommend
outdoor shelter installations that depend on internal air
for combustion. Combustion air should be ducted to the
heater from outside the structure.
Outside Air Supply: When combustion air is
supplied directly through an outside wall, each opening
should have a minimum free area of one square inch
per 4,000 BTU/h (1.2kW) input of the total input rating
of all appliances in the enclosed area. If air is provided
through horizontal ducts, each opening and duct must
provide one square inch of flow area for each 2000
BTU/h (0.6 kW). These requirements are summarized
in Table 3. Note that the areas specified are net free
areas and should be increased by 50 percent when the
openings are covered by screens, louvers, grills or
other protective covers (see Figure 5 and Table 3).
Note: In Canada, follow Canadian Standard,
CAN/CSA-B149.1 or local codes.
Exhaust Fans or Vents: Any equipment which
exhausts air from the room where the heater is
installed can deplete the combustion air supply or
reverse the natural draft action of the venting system.
This could cause flue products to accumulate in the
room. Additional air must be supplied to compensate
for such exhaust.
The information in Table 3 is not applicable in
installations where exhaust fans or blowers of any type
are used. Such installations must be designed by
qualified engineers.
If a blower or fan is used to supply air to the
room, the installer should make sure it does not create
drafts which could cause nuisance shutdowns of the
pilot.
The heater must be completely isolated and
protected from any source of corrosive chemical
fumes such as those emitted by trichlorethylene,
perchloroethylene, chlorine, etc.
WARNING
Do not store any chemicals, cleaners, or other
corrosive material near combustion air
openings or in the room. Avoid locating dryer
vents in the vicinity of combustion air openings.
Failure to prevent corrosive materials from
mixing with combustion air can result in
reduced heater life and unsafe heater
operation.
AVERTISSEMENT
N’entreposer aucun produit chimique, produit
nettoyant ou produit corrosif à proximité des
bouches d’air de combustion ou dans la pièce.
Éviter de placer des tuyaux de ventilation pour
sécheuse à proximité des bouches d’air de
combustion. Le fait de laisser des matières
corrosives se mélanger à l’air de combustion
risque de réduire le cycle de vie de l’appareil
de chauffage et de compromettre son
fonctionnement.
3.2 Vent Pipe Sizing and General
Installation
3.2.1. Outdoor Installations
For outdoor installations, exhaust venting
considerations will determine the placement of the
heater (See Section 2.3.4). If the heater cannot be
placed so as to meet the requirements stated in Section
2.3.4, a vent pipe and cap may be added to the heater
to move the exhaust vent opening to a position that
complies with the requirements. When the heater is
installed in areas of high wind or when unavoidably
installed near a vertical obstruction where
downdrafting may occur, it may be desirable to add a
vent cap directly to the top of the heater. In all cases,
vent pipes and caps must be of the same diameter as
the exhaust outlet of the heater. Approved vent caps
may be obtained through your Jandy distributor.
Page 9
3.2.2. Indoor and Outdoor Shelter
Installations
WARNING
Vent pipe diameter must be as required by the
National fuel Gas Code ANSI Z223.1 or the
Canadian Installation Codes for Gas
Appliances CAN/CSA-B149.1. Undersize pipe
can result in inadequate venting and oversize
pipe can result in vent condensation. In either
case the result can be release of combustion
products to the indoors. This can cause
serious injury or death by carbon monoxide
poisoning or asphyxiation.
AVERTISSEMENT
Le diamètre des tuyaux de ventilation doit
répondre aux exigences du National Fuel Gas
Code ANSI Z223.1 ou du code canadien des
installations des appareils à gaz CAN/CSAB149.1. Des tuyaux trop petits risquent
d’entraîner une ventilation inadéquate et des
tuyaux trop gros risquent de provoquer une
condensation dans les tuyaux. Dans un cas
comme dans l’autre, des produits de
combustion risquent de s’échapper dans le
bâtiment et causer des blessures graves ou
l’asphyxie par le monoxyde de carbone.
All indoor installations and outdoor shelter
installations require the addition of a factory approved
drafthood. The drafthood must be installed without
modification.
All vent installations must be made in accordance
with all local, state or provincial codes and with:
1.
Chapter covering "Venting of Equipment" of the
national Fuel Gas Code, ANSI 223.1 latest
edition , or the applicable provisions of the local
building codes.
2.
In Canada , CAN/CSA-B149.1.
Avoid long horizontal runs of the vent pipe, and
90° elbows, reductions and restrictions. Horizontal runs
should have at least a 1/4 inch rise per foot (20mm
per meter) in the direction of flow.
Avoid terminating heater vents near air conditioning or air supply fans. The fans can pick up exhaust
flue products from the heater and return them inside
the building, creating a possible health hazard.
Do not locate the vent terminal where flue
products could strike against building materials and
cause degradation.
Vent opening should be well away from trees or
other obstructions that would prevent free air flow to
and from vent terminal. Do not terminate the vent
under decks, stairways, or car ports.
Be sure to support all venting so that connections
Page 10
will not separate and so that the weight of the vent
pipe does not rest on the heater draft hood. All connections should be made with rustproof sheet metal
screws. Do not weld or fasten the vent pipe to the
heater draft hood. The draft hood and heater top must
be easily removable for normal heater service and
inspection.
The draft hood outlet is to be connected to an
unobstructed vent pipe of the same diameter, terminating outside the building. The vent must terminate at
least two (2) feet (0.61 m) above the highest point of
the roof or other object that is within ten (10) feet
(3.05 m) of the vent termination. The vent pipe must
have a listed vent cap which allows a full equivalent
opening for flue products (see Figure 5). The top of
the vent cap must be at least five feet in vertical height
above the drafthood outlet.
Type “B” double wall or equivalent vent pipe is
recommended. However, single wall metal vent pipe
may be used as specified in the latest edition of the
National Fuel Gas Code ANSI Z223.1 or in Canada
CAN/CSA-B149.1

1.
Gas piping installation must be in accordance
with the latest edition of ANSI Z223.1 and all
local codes. In Canada, the installation must be in
accordance with CAN/CSA-B149.1 and all local
codes that apply.
2.
Check the gas supply to be sure that it is the
same as the gas indicated on the heater’s rating
plate. Lite2 LG heaters, as shipped from the
factory, are certified to operate within the
altitude range indicated on the rating plate. If a
field conversion to a different altitude range
should be necessary, manifold kits are available
for changing the altitude range of the heater. See
Table 1 in section 1.7.1 of this manual to determine the correct altitude designation for your
heater. Refer to Section 11 “Parts List” to order
the correct part number of the manifold kit
needed. When changing the altitude range of the
heater, be sure to fill out the altitude conversion
label, included in the kit. Apply the label on the
inner panel of the heater, next to the original
rating plate.
IMPORTANT NOTE: Do not use sheet metal
screws at the snap lock joints of Type B gas
vents.
When venting multiple appliances through one
common duct, each appliance must have it’s own vent
temperature limit switch. All vent limit switches must
be wired in series so as to prevent any appliance from
firing in the event of a blocked vent. Refer to ANSI
Z223.1 or, in Canada, to CAN/CSA-B149.1 for more
information on multiple venting.
3.2.3 Inspection and Replacement of
Existing Vent System with New
Components
If the Lite2 is being installed to replace an
existing pool heater, it is recommended that a new
appropriate venting system be installed with the new
heater. However, if an existing venting system must be
used, be sure to carefully inspect the venting system to
ensure that it is in good condition and continues to be
appropriate for the Lite2 heater. Replace any parts
that are not in good and serviceable condition with new
parts before completing the pool heater installation.

Before operating the heater, test the complete
gas supply system and all connections for leaks
using a soap solution. Do not use an open flame.
CAUTION
Some leak test solutions (including soap and
water) may cause corrosion or stress cracking.
Rinse the piping with water after testing.
Figure 6. The proper design for a sediment trap/drip leg.
4.
Install a sediment trap (drip leg) ahead of the gas
controls (see Figure 6). Fit the trap with a
threaded cap which can be removed for cleaning.
5.
Install a manual gas shutoff valve for service and
safety. Do not use a restrictive gas cock. DO
NOT USE FLEXIBLE GAS PIPING, it will
restrict the gas flow to the heater.
6.
Disconnect the heater and its individual shutoff
valve from the gas supply system during pressure
testing of the system at pressures higher than 1/2
pounds per square inch (psi) (3.45 kilopascals
[kPa]). If the test pressure is equal to or less
than 1/2 psi (3.45 kPa), close the manual shutoff
valve on the heater during the piping pressure
test.
7.
If the gas supply pressure is less than required,
check for undersized pipe between the meter and
the heater, a restrictive fitting, or an undersized
gas meter. Gas supply pressures to the heater
are listed in Table 5.
ATTENTION
Certaines solutions d’essai d’étanchéité (y
compris l’eau et le savon) peuvent causer de la
corrosion ou de la fissuration. Rincez les
tuyaux à l’eau après l’essai d’étanchéité.
4.2 Manifold Pressure
Confirm that gas supply pressure is correct. If
the gas supply pressure is less than required, check for
undersized pipe between the meter and the heater, a
restrictive fitting, or an undersized gas meter. Gas
supply pressures to the heater, when it is operating,
are listed in Table 5.
CAUTION
Manifold gas pressure for the Lite2 Lg natural
gas heaters should be set at 4" WC. Propane
heaters should be set to 9" WC.
ATTENTION
La pression du collecteur de pression pour les
systèmes de chauffage au gaz naturel devrait
être de 4'’ WC. Pour les sytèmes de chauffage
au gaz propane devrait être de 9'’ WC.
The manifold pressure may be checked by connecting a manometer to the pressure port on the outlet
side of the valve. You will need to remove the 1/8"
Page 12
NPT protective plug form the port and install the
appropriate 1/8" NPT fitting to connect your manometer. The pressure will be zero when the heater is not
running. When the heater is operating the manifold gas
pressure should be 4.0" WC for natural gas heaters
and 9.0" WC for LP gas heaters.
To adjust the manifold gas pressure, first remove
the slotted cap on the top of the gas valve to the right
of the control knob. Under the slotted cap is a slotted
plastic screw which increases the manifold pressure
when turned clockwise and decreases the manifold
pressure when turned counterclockwise.
After measurements, and adjustments if necessary, have been made, make sure to replace the 1/8"
NPT plug on the manifold pressure ports, and the cap
on the manifold pressure adjustment screw. It is
extremely important to replace these parts before
leaving the installation. Failure to do so can result in
damage to property or injury or death.
With the heater firing, the pressure must be
within the range shown in Table 5. Also check the
pressure with the heater off.
4.3 Special Precautions for LP Gas
LP Gas is heavier than air and can therefore
more readily collect or “pool” in enclosed areas if
provision for proper ventilation is not made. Installation
of pool heaters in enclosed areas such as pits is not
recommended. However, if such an installation is
required be sure to pay special attention to proper
ventilation for LP gas. Locate heaters a safe distance
from LP gas cylinders and filling equipment. In the
United States, consult the "National Fuel Gas Code"
(NFPA 54 / ANSI Z223.1, latest edition) or in Canada,
the "Natural Gas and Propane Installation Code"
(CAN/CSA-B149.1), and any local codes and fire
protection authorities about specific installation restrictions in your area.
SECTION 5.
Water Connections
5.1 Water Piping
Figure 7 illustrates typical piping for pool equipment in pool/spa combination pools.
For normal installations, do not install a shutoff
valve or any kind of variable restriction in the water
piping between the heater outlet and the pool/spa. In
special installations where a shut-off valve, diverter
valve or other variable restriction is required in the
plumbing between the heater outlet and the pool,
Water Pik Technologies recommends the installation
of a pressure relief valve on the heater (see Section
5.6).
Arrangement of pool system components other
than as illustrated in these diagrams can affect the
operation of the heater’s water pressure switch.
Location of the heater above or below the pool water
surface can also affect operation of the switch. In
general, the pressure switch can be adjusted to
accommodate this effect if the heater water connections are no more than six feet below the pool water
surface and no more than 15 feet above it. See
instructions for pressure switch adjustment (Section
7.5) in the heater start-up section of this manual for
more information about this.
Note that when pool equipment is located below
Note: When using metal pipe as heat sink, join metal and PVC/CPVC, using metal male and PVC/CPVC female connection.

the pool surface a leak can result in large scale water
loss or flooding. Water Pik Technologies cannot be
responsible for such water loss or flooding or the
damage caused by it.
For special installations such as water connections below the water level of the pool, or for other
questions contact the Jandy Technical Service department at (707)-776-8200 ext 260.
5.2 Check Valve Installation
The heater must be protected from backsiphoning of water, which can result in dry starts. If
there is any chance of back-siphoning, provide a check
valve between the pool and the filter pump inlet.
Page 13
When an automatic chemical feeder is installed
in the plumbing, it must be installed downstream of the
heater (see Section 5.7). A check valve must be
installed between the heater and the chemical feeder
to prevent back-siphoning of chemically saturated
water into the heater where it will damage the components.
5.3 Automatic Flow Control Valve
The inlet/outlet header of the Lite2 comes
equipped with an automatic flow control valve. The
automatic flow control valve maintains the proper flow
through the heater at rates up to approximately 125
Gallons Per Minute (GPM) (474 liters per minute
[LPM]). If the filter system flow rate is higher than
approximately 125 GPM (474 LPM), install a manual
bypass valve (see Figure 7), then perform a temperature rise test (see Section 7.6) and adjust the flow
using the bypass valve until the proper temperature
rise is obtained.
5.4 Reversible Water Connections
Water Pik Technologies ships the Lite2 heater
with the water connections on the right side. The Lite2
heater can be installed with the water connections on
either side. It could be necessary, or helpful, to switch
the connections to the left side to improve access for
installation and service. Perform this modification
before installing the heater using the following procedures:

5.6 Pressure Relief Valve
A pressure relief valve (PRV) is recommended in
all installations and is mandatory in any installation in
which the water flow can be shut off between the
heater outlet and the pool/spa.
A pressure relief valve is not supplied with the
heater. However, it may be required by local codes.
The pressure rating of the valve should be at or below
the lowest working pressure of any component in the
filter system. Any pressure relief valve installed must
comply with provisions of the Standard described in
ANSI Z21.22 for the United States, or CSA 4.4 in
Canada.
To install a pressure relief valve, do the following:
1.
Remove the 3/4 inch (19 mm) brass plug located
on the top of the inlet/outlet header (see Figure
15).
2.
Install the pressure relief valve in the threaded
hole from which the plug was removed.
3.
Be sure that the exhaust port of the PRV is
plumbed so that any hot water is directed safely
away from any public areas and away from any
area occupied during servicing.
The Lite2 heater is manufactured with materials
that are not compatible with high concentrations of
ozone, chlorine, bromine, or other sanitizing chemicals. Heater damage caused by excessive chemicals or
improper ozonization is not covered by the Water Pik
Technologies warranty. Be sure to adhere to the
following:
•
When ozone is injected upstream of the heater,
install an offgas mixing chamber, or an ozone
bypass system between the heater and the ozone
injector to prevent ozone and air from entering
the heater.
•
When chemical feeders are used, plumb the
feeder downstream of the heater and install an inline check valve between the heater and the
feeder (a minimum of 18" is required between
the heater and the check valve).
•
Never deposit chemicals directly in the pool
skimmer.

Electrical
WARNING
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Verify proper operation after servicing.
AVERTISSEMENT
Au moment de l'entretien des commandes,
étiquetez tous les fils avant de les débrancher.
Des erreurs de câblage peuvent entraîner un
fonctionnement inadéquat et dangereux.
6.1 Main Power
The Lite2 model LG heater does not require an
external source of electrical power to operate. The
power for the gas valve and safety circuit are generated by a thermopile. The thermopile generates a
millivolt signal when heated by the pilot flame. Figure
17 shows the internal electrical wiring diagram and
schematic of the heater.
Page 17
The length of the wire between the heater and
the time clock should not exceed 10-15 feet (4.57 m).
The contact points of the time clock switch should be
silver, or a low resistance alloy.
6.2 Bonding
CAUTION
This heater must be connected to a bonding
grid with a solid copper wire not smaller in
diameter than 8 ga.
ATTENTION
L’appareil de chauffage doit être connecté à
une grille de mise à la terre par un fil de cuivre
d’un diamètre de calibre minimal 8.
The National Electrical Code and most other
codes require that all metallic components of a pool
structure, including reinforcing steel, metal fittings
and above ground equipment be bonded together with
a solid copper conductor not smaller than a number 8
wire. The heater, along with pumps and other such
equipment must be connected to this bonding grid. A
special labeled bonding lug is provided on the right side
of the heater to accommodate this requirement.
6.3 Auxiliary Time Clock Wiring
If you install a time clock to control the filter
pump operation, it is recommended that the time clock
have its own low voltage (Fireman’s) switch to turn
off the heater before turning off the pump. The switch
should shut off the heater about 15 minutes before the
filter pump shuts off. This will allow for a more
efficient operation by removing any residual heat
contained in the heat exchanger back to the pool.
To install a time clock auxiliary switch into the
heater wires (see Figure 16):
1.
Remove heater door.
2.
Remove the factory installed wire between
terminals 1 and 2 on the terminal strip (see
Figure 16).
3.
Connect the wires from the time clock auxiliary
switch to the two terminals. Use American Wire
Gage (AWG) No. 14 gauge stranded copper wire
with a temperature rating of 221°F (105°C) or
greater.
Figure 16. Time Clock Wiring.
SECTION 7.
Operating Instructions
7.1 Normal Operation
The Lite2 model LG heaters are capable of
automatic operation based on a call for heat at a preset
temperature. The heater has an internal safety system
which allows operation in a variety of conditions and
prevents operation when certain adverse conditions are
encountered.
When the heater's pilot is lit and the pilot generator is providing a millivolt signal to the safety circuit,
water is flowing through the heater, and the temperature of the water entering the heater is below the
temperature control setting, an operating cycle is
initiated by the automatic control. The temperature
control circuit is closed, activating the gas valve and
the gas valve is opened. Gas flows through the burners, is mixed with air in the combustion chamber, and
is ignited by the pilot. Operation will continue until
the temperature of the water entering the heater
reaches the temperature control setting.
If ignition is unsuccessful, or if the flame fails
during normal operation, the temperature control
circuit opens and shuts off the gas valve.

CAUTION
Should overheating occur or the gas supply fail
to shut off, turn off the manual gas control
valve to the heater.
ATTENTION
En cas de surchauffe ou si l'alimentation en
gaz ne s'arrête pas, fermez manuellement le
robinet d'arrêt de l'admission de gaz.
CAUTION
Do not attempt repairs on the gas controls or
appliance. Tampering is dangerous and voids
all warranties.
ATTENTION
Ne tentez pas d’effectuer des réparations au
système de régulation du débit du gaz ou à
l’appareil. Toute modification non autorisée est
dangereuse et entraîne l’annulation de toutes
les garanties.
CAUTION
Keep all objects off the top of the heater.
Blocking air flow could damage the heater, and
may void the warranty.
ATTENTION
Ne posez aucun objet sur le dessus de
l’appareil. Il pourrait empêcher la circulation de
l’air, ce qui risquerait d’endommager l’appareil
et d’annuler la garantie.
Page 19
WARNING
Vent pipes, draft hoods, and heater tops get
hot! These surfaces can cause serious burns.
Do not touch these surfaces while the heater is
in operation. Adding a vent cap reduces the
temperature on the top.
AVERTISSEMENT
Les tuyaux d’aération et le dessus de l’appareil
deviennent chauds! Ils peuvent causer de
graves brûlures. Ne touchez pas à ces
surfaces lorsque l’appareil est en marche.
WARNING
For your safety, when starting the heater, keep
your head and face well away from the lower
firebox opening to prevent any risk of personal
injury.
AVERTISSEMENT
Pour votre sécurité personnelle lorsque vous
mettez l’appareil en marche, tenez votre tête et
votre visage loin du brûleur pour éviter tout
risque de blessure.
Be sure that there is water in the pool and that
the surface level is above the skimmer or other inlet of
the pool’s filter system.
Confirm that pool water is flowing normally
through the pool system and equipment. With any
new pool or spa installation, operate the filter pump
with the heater off long enough to completely clean
the water. This will remove any installation residue
from the water. Clean the filter at the end of this
operation before starting the heater. Start the heater
in accordance with the Operating Instructions section
of this manual, with particular attention to the lighting
and shutdown instructions and temperature control
operation.
When raising the temperature of a cold pool,
remove all time clock settings. This lets the filter
system and heater operate continuously until the water
reaches the temperature setting on the temperature
control. When that happens, the heater will automatically shut off, but the filter pump will keep running.
When the heater starts, immediately feel the
outlet header of the heater to confirm that there is
adequate water flow. The header should not be hot.
Normally, water temperature will rise only a few
degrees as it passes through the heater, and a “hot”
header or pipe indicates low water flow.
Page 20
WARNING
When the heater is fired for the first time, the
combustion chamber refractory binder material
is driven out by the heat of the flame. White
smoke and/or sharp odors may be emitted from
the vent during this period. Do not inhale
combustion product fumes at any time, and
especially when these fumes are being
emitted. This "burn-in" period will last only a
few minutes.
AVERTISSEMENT
Lorsque l’appareil est mis en marche pour la
première fois, le matériau liant réfractaire de la
chambre de combustion est expulsé par la
chaleur de la flamme. De la fumée blanche et
de fortes odeurs peuvent se dégager du tuyau
d’aération à ce moment-là. N’inhalez les
fumées de combustion à aucun moment,
surtout au moment où elles sont émises. Cette
période de combustion ne durera que quelques
minutes.
7.3 Lighting and Shutdown Procedures
Before starting your heater, be sure that you are
familiar with the setting and operation of the heater
controls. Once the controls are set to your preferences,
follow the instructions outlined on the following page.
Read and follow all safety instructions first.
A more detailed set of instructions of the operation of the LG controller follows in the next section.
NOTE: If your heater is configured to operate
on LP gas and the LP tank runs out of fuel, turn
off gas at the heater. After the tank is refilled,
the heater must be relit following the
instructions found on the inside of the heater. A
copy of these instructions appear on the
following page. DO NOT attempt repairs on the
gas control or heater. Tampering is dangerous
and voids all warranties.
WARNING
Do not attempt to operate the heater with the
door off. Doing so may cause severe bodily
injury.
AVERTISSEMENT
Ne tentez pas d'opérer l’appareil sans que la
porte soit en place. Vous pourriez être victime
de blessures corporelles graves.
Figure 18. Temperature controls.
7.4 Turning the Heater On/Off and
Setting the temperature control
The temperature control (see Figure 18) is
calibrated at the factory and covers a range from
approximately 70°F to 104°F (21°C to 40°C). Use an
accurate pool thermometer to determine the best
water temperature for your uses.
The Lite2 temperature control panel has a rocker
switch to turn the heater on and off. It also has a rotary
dial to set the desired thermostat setting (see Figure
18).
Once the heater has been lit by following the
safety and lighting procedures in Section 7.3, set the
toggle switch on the control panel to "ON" to start the
heater operation. If the heater senses that the pump is
on and the thermostat setting is higher than the temperature of the pool/spa water, the pilot will ignite the
main burners.
NOTE: The heater is designed to run only
when the filter pump is running. If the heater
does not immediately turn off when the pump
turns off, turn the heater off at the control panel.
The heater's pressure switch may need
adjusting (see Section 7.5)
Once the pool/spa water temperature reaches
the thermostat setting, the heater will automatically
stop firing. As the pool/spa water temperature falls
below the thermostat setting the heater will once again
start the heating cycle.
Rotate the thermostat dial clockwise to increase
the temperature setting and counterclockwise to
decrease the setting. It may take several attempts to set
the thermostat dial to the desired temperature. Be sure
to use an accurate thermometer to measure water
temperature. Once the desired temperature setting is
found, loosen the screw on the Temp-Lok ring and
rotate the ring until the stop rests against the knob.
Tighten the screw to hold the knob in position. This
will prevent accidental moving of the dial and possible
overheating of the water.

Page 22
Make sure the pool filter is clean before making
any pressure switch adjustment. A dirty filter will
restrict the water flow and the pressure switch cannot
be adjusted properly. To adjust the pressure switch:
Figure 19. Pressure switch adjustment.
1.
Set the control panel rocker switch to the OFF
position (see Figure 18).
2.
Set the Pool temperature control to the Max
position.
3.
Turn filter pump on. If a two-speed pump is
used, make sure it is at high speed.
NOTE: If using a two-speed pump, the heater
should not be allowed to fire on low speed.
IMPORTANT: The temperature controls
cannot be calibrated in the field. If the control is faulty,
shut down the heater by following the procedures in
Section 7.3 and have a qualified service technician
replace the control. DO NOT use the thermostat
switch to completely shut down the heater.
4.
Set the rocker switch to ON. Heater should start.
5.
Pry out the top rubber dust plug on the top of the
pressure switch.
7.5 Water Pressure Switch Adjustment
6.
Use a 7/32 inch (5.55 mm) Allen wrench to turn
the adjustment screw very slowly clockwise until
the heater goes off (see Figure 19).
7.
Slowly turn the pressure switch adjustment
screw counterclockwise one-quarter turn. The
heater should come back on.
8.
Check the adjustment by turning the filter pump
OFF. The heater should shut off immediately. If
it does not, restart the filter pump and repeat
Steps 6 and 7. Check the adjustment again.
9.
Return the pool temperature control to the
desired temperature.
CAUTION
The water pressure switch should be adjusted
to turn the heater off when the pump is off.
Setting the switch to close at too low of a flow
can damage the appliance. Adjust the switch to
turn the heater off, not on.
ATTENTION
Le manocontact de pression d’eau doit être
réglé de façon à ce que l’appareil cesse de
fonctionner si la pompe s’arrête. Si le
manocontact est réglé pour se fermer lorsque
le débit d’eau est trop faible, l’appareil risque de
s’endommager. Réglez le manocontact pour
qu’il arrête l’appareil, et non pour qu’il le mette
en marche.
The pressure switch is preset at the factory for
activation at 2 psi (14 kPa). Adjust the pressure switch
only if any part of the filter system piping is 3 feet
(0.91 m) or more above the top of the heater jacket.
Do not adjust the pressure switch if the heater is
installed more than 15 feet (4.57 m) below or 6 feet
(1.83 m) above the pool surface. Consult your local
Jandy representative for recommendations.
On some installations, the piping from the heater
to the pool is very short. The back pressure could be
too low to trigger the pressure switch. If this happens,
it may be necessary to install a directional fitting or
elbows where the return line enters the pool. This will
increase back pressure enough for the heater to operate
properly.
7.6 Temperature Rise
The automatic flow control valve (see Section
5.2) maintains the proper flow through the heater at
rates up to approximately 125 gallons per minute
(GPM) (475 liters per minute [LPM]).
A temperature rise test confirms proper water
flow through the heater. The temperature rise is the
difference between the temperature of the pool or spa
water before and after heating, as measured in the
header. Perform the following temperature rise test
when the installation is complete:
1.
Make sure the pool filter is clean.
2.
Set the rocker switch on the temperature control
panel (see Figure 18) to OFF.
3.
Turn the filter pump OFF.
4.
Remove the drain plug located on the inlet/outlet
header of the heater and replace it with a Pete's
plug (see Figure 15).
Page 23
5.
Insert a pocket thermometer (see Figure 14)
through the Pete's plug into the header.
13. If the temperature rise is within the correct range,
complete the procedure as follows:
6.
Turn the filter pump ON and wait 3 minutes. The
heater remains OFF. This allows water from the
pool to reach the heater.
7.
Record the temperature indicated by the thermometer (cold water).
a.
b.
c.
d.
8.
Turn the heater ON following the lighting
instructions found on the inside of the heater.
If a manual bypass valve is installed, use the
following procedures to adjust the bypass valve:
9.
Allow the heater to run for about 3 minutes.
Record the new temperature reading (heated
water).
1.
Clean pool filter.
2.
Remove drain plug located on the inlet/outlet
header of the heater and replace it with a Pete's
plug.
3.
Insert a pocket thermometer (see Figure 15)
through the Pete's plug into the header.
4.
Close manual bypass valve.
5.
Turn on the temperature control to the OFF
position.
6.
Repeat steps 6 through 10 of the temperature
rise test (see Section 7.6).
7.
If the temperature rise is below the minimum
stated in Table 6, open the manual bypass valve
until temp rise climbs between the min. and max.
range for your size heater. If the minimum
temperature rise stated in Table 6 cannot be
reached with the manual bypass fully open, then
the gas supply volume is too low.
8.
If the temperature rise is above the maximum,
there is not enough water flowing through the
heater. Check for clogging in the water filter or
restriction in the water pipes.
9.
Once the temperature rise is within the correct
range, safety wire the handle of the manual
bypass valve in place and tag the valve to
prevent change in the water flow.
10. Subtract the first temperature reading (cold
water) from the second temperature reading
(heated water). The difference between the two
readings is the temperature rise. The temperature rise should be within the range shown in
Table 6.
11. If the temperature rise is below the minimum
range indicated, two possibilities arise:
a.
The supply gas volume is too low.
b.
The system's water flow exceeds 125 GPM
(475 LPM), and requires a manual bypass valve
for proper operation (see Figure 7).
7.7 Adjusting the Manual Bypass Valve
12. If the temperature rise is above the maximum,
there is not enough water flowing through the
heater. Check for clogging in the water filter or
restriction in the water pipes.
CAUTION
Operating the heater with the temperature rise
above maximum or below the minimum can
damage the heater and may void the warranty.
ATTENTION
Opérer le chauffe-piscine au-dessus du niveau
de température maximale ou sous le niveau de
température minimale recommandée, peut
endommager le chauffe-piscine et ainsi annuler
la garantie.
Turn heater OFF.
Wait 3 minutes, turn filter pump OFF.
Remove thermometer and Pete's plug.
Replace the drain plug.

8.1 Water Chemistry
The mineral content of swimming pool water
increases daily due to natural evaporation and the
addition of sanitizing chemicals. If the mineral concentration in the pool gets too high, the excess minerals
will deposit on the walls of the pool, in the filter
system, and in the heater tubes.
Page 24
Figure 20. Heater drain locations.
The proper chemical balance in spa water is
more critical than in a swimming pool heater operation. Due to the spa’s size, high water temperature
and heavy usage, chemical values in a spa can vary
greatly. This chemical imbalance can result in
unsanitary water conditions, and affect the life of the
heater.
Proper chemical balances are necessary for
sanitary bathing conditions as well as ensuring your
heater’s long life. Kits are available from your local
pool supply dealer for making the various tests for
mineral content. One of these kits will detect copper
in the system. This is usually a warning that corrosion
is taking place, possibly due to a low pH value
combined with other chemistry problems. The
condition can be corrected by changing the spa water
and closely monitoring the pH factor and chemical
properties of the water. Be sure to keep your
chemical levels within the values indicated in Table 7.
Water Pik Technologies does not warrant heat
exchangers damaged by corrosive chemical
levels or excess dissolved solids in pool or spa
water.
For spas, it is also necessary to perform water
changes in addition to chemical treatment. It is
recommended to change the spa water every 60 days
for light usage and every 30 days if usage is heavy.
8.2 Seasonal Care
CAUTION
Do not operate this heater outdoors at
temperatures below 20 degrees Fahrenheit (°F)
(-7 degrees Celsius [°C]).
ATTENTION
Ne faites pas fonctionner cet appareil à
l’extérieur à des températures inférieures à 20
degrés Fahrenheit (oF) (-7 degrés Celsius [oC]).
8.2.1 Spring and Fall Operation
During periods when the pool is only going to be
used occasionally, turn the temperature control down to
the MIN setting. This prevents the pool water from
becoming chilled, and minimizes the time required to
raise the pool water back up to the desired temperature.
In areas subject to only short freeze periods, turn
off the heater and run the pump continuously for the
length of the freeze period.
If the heater is not going to be used for a long
period of time, shut it down completely. Follow the
instructions found on the inside of the heater, or page
21 of this manual.

as follows:
1.
Attach the copper tubing to the pressure switch
(see Figure 21).
2.
Tighten the drain plugs.
3.
Turn on the filter pump and circulate water
through the heater for 5 minutes. Check for leaks
while circulating.
4.
Turn on the main gas supply valve to the heater,
outside the heater jacket.
5.
Turn on the heater following the lighting instructions found on the inside of the heater, or page 21
of this manual.
8.3 Inspection and Service
The Lite2 LG heater is designed and constructed
heater to provide long performance life when installed
and operated properly under normal conditions.
Periodic inspections, especially at spring start-up, are
important to keep your heater running safely and
efficiently through the years. Improper maintenance
Page 25
can result in conditions where nausea or asphyxiation
from carbon monoxide or flue gases could cause
severe injury, property damage or death.
WARNING
Improper installation or maintenance can cause
nausea or asphyxiation from carbon monoxide
in flue gases which could result in severe
injury, or death.

8.3.1 Owner Inspection
Water Pik Technologies recommends that you
inspect the heater on a continual basis and especially
after abnormal weather conditions. The following basic
guidelines are suggested for your inspection:
1.
Keep the top and surrounding area of the heater
clear of all debris.
2.
Keep the area around and beneath the heater
clean and free of all combustible materials such
as paper, leaves, etc.
3.
Do not store or use gasoline or other flammable
vapors, liquids or chemicals in the vicinity of
this or any other appliance.
Ne pas entreposer ni utiliser d'essence ni d'autres
vapeurs ou liquides inflammables à proximité de
cet appareil ou de tout autre appareil.
4.
Do not use the heater if any part has been under
water. Immediately call a qualified professional
technician to inspect the heater and replace any
part of the control system which has been
submerged.
N'utilisez pas cet appareil s'il a été plongé dans
l'eau, même partiellement. Faites inspecter
l'appareil par un technicien qualifié et remplacez
toute partie du système de contrôle et toute
commande qui ont été plongés dans l'eau.
5.
If the heater is equipped with a pressure relief
valve, check for corrosion in and around the
valve. With the filter pump on, lift the release
lever on the top of the valve to make sure that
water runs freely through it. If corrosion is
found, replace the pressure relief valve. When
Page 26
replacing the valve, be sure that the pump is off.
Install the valve so that the discharge is directed
away from any area that may be damaged by
water.
6.
Be sure all combustion air and ventilation
openings are not blocked. Check for spider webs
and other debris inside the heater, in the vents on
all sides of the heater jacket and in the exhaust
outlet– especially after a long period of nonuse.
8.3.2. Professional Inspection
Inspections performed at least once a year by a
qualified technician are required to maintain your
heater's safe and efficient operation. The following
basic safety checks must be performed.
1.
Inspect the venting system for blockage, leakage,
and corrosion.
2.
Inspect burners and verify that they are clean.
Clean with a wire brush if necessary to remove
debris.
3.
Check for spider webs and other debris in the
pilot and main burner orifices - especially at
spring start-up.
4.
Check for loose or broken wires and terminal
connections.
5.
Make sure that the pressure switch operates
properly by shutting the filter pump off and on a
few times. The burner should go off immediately
after the pump stops. An ignition sequence
should start shortly after the pump is turned back
on.
6.
Make a visual check of the main burner flame.
The flame can be seen in a mirror arrangement
held beneath the burners. The flame should be
a. Blue in color.
b. 1 to 4 inches (25mm to 102mm) above burner
surface (see Figure 22).
7.
Inspect the gas and electronic controls, including
the following:
a. High temperature limit switch
b. Water pressure switch
c. Automatic gas valve
d. Fusible Link
e. Temperature control
f. Control circuit fuse
8.
Perform a temperature rise test in accordance
with Section 7.6.
9.
If the heater is equipped with a pressure relief
valve, check for corrosion in and around the
valve. With the filter pump on, lift the release
lever on the top of the valve to make sure that
water runs freely through it. If corrosion is found,
replace the pressure relief valve. When replacing
the valve, be sure that the pump is off. Install the
valve so that the discharge is directed away from
any area that may be damaged by water.
10. Inspect the external surfaces of the heat exchanger tubes for black carbon soot buildup by
placing a mirror between and under the burners
when the heater is firing. Remove any soot that
has collected on the tubes, and correct the cause.
NOTE: After installation and first start-up,
check the heat exchanger for black carbon soot
buildup after the following periods of operation:
24 hours, 7 days, 30 days, 90 days, and once
every 6 months thereafter.
11. Conduct a normal operating cycle and observe
that the sequence proceeds as intended.
CAUTION
For your safety, when starting the heater, keep
your head and face away from the burner area
opening to prevent any risk of personal injury.

dommages à la propriété. Pour cette raison,
l’appareil de chauffage doit être entretenu et
réparé uniquement par un technicien

10.1 General Information
A qualified professional technician must service
the Lite2 model LG pool heater using Water Pik
Technologies, Inc. service procedures. Before calling
for service, however, the owner should check for
obvious problems. The other components in the pool
system, including pump, filters and strainers, water
valves, gas supply and time clocks have an effect on
heater operation.
Confirm that the LG heater control switch is set
to 'ON' and that the temperature control knob is set
high enough to make the heater operate. Make sure the
pump is operating, that the filter and strainers are not
clogged, that there are no mis-positioned water valves,
that the gas is not shut off and that time clocks are
properly adjusted. Also be sure that there is no blockage of the vent or louvers which supply combustion
air to the burners.
10.2 Natural-Draft Combustion System
The Lite2 model LG pool heater has an atmospheric combustion system. This system is illustrated
in Figure 23.
As the heated exhaust gases rise out of the
combustion chamber, flow is created through the
system and fresh combustion air is drawn into the
heater through the louvers cut into the front and sides
of the heater. Gas is forced through an orifice into the
open end of a burner. When the gas flows into the
burner, a “negative” pressure is created at the opening
of the burner. This negative pressure pulls air into the
burner with the gas and mixes the two together. As the
gas/air mixture flow through the burner ports it is
ignited in the combustion chamber. Hot combustion
products then rise through a highly efficient heat
exchanger. Combustion products then enter a flue
collector and are directed to the outdoors through the
grate top of the heater or a vent pipe and cap.
10.3 Heater Components and Their
Operation
1.
Gas Valve / Regulator - The gas valve controls
gas flow into the manifold. It provides flow only
when the temperature controls require heat and
only if all safety controls enable operation. It is
also a positive pressure regulator. It regulates
the gas pressure in the manifold to specifications
addressed earlier in this manual. This is necessary for proper operation of the burner system.
2.
LG Temperature Control- The Jandy LG
controller is an electronic control which senses
water temperature by means of a thermistor and
controls heater operation to bring the water to the

desired temperature. The desired temperature is
set by rotating a knob on the face of the control
panel. To achieve accurate water temperatures,
the pool/spa water must be monitored with an
accurate pool thermometer.
5.
Limit Switches - Two limit switches prevent
excessive water temperature - one within the heat
exchanger and one for water leaving the heater.
If either senses excessive temperature, burner
operation is interrupted.
Pilot/Pilot Ignition
6.
Water Pressure Switch - This control senses
whether or not water is available to the heater by
measuring back pressure inside of the heat
exchanger. If the pool water pump fails or the
water filter is blocked, the pressure switch
prevents operation of the burner.
7.
Fusible Link - This is a single-use switch which
detects abnormal temperature in the component
vestibule. It is a fusible link which is held to the
inner panel just above the burner tray by a sheet
metal bracket. Excessive temperature in the
component compartment, possibly due to a
blocked flue or flame roll-out, will cause the link
to fail. This opens the safety circuit which shuts
off the gas valve and shuts the heater down.
The LG heater relies on a standing pilot to ignite
the burners when the temperature control calls
for heat. When lit the pilot receives a constant
flow of gas from the gas valve. If the pilot
exstinguishes, the gas valve is automatically
signalled to stop the flow of gas to the pilot and
the burners to prevent a gas build up in the
heater. Igniting the pilot is achieved by means of
a piezo spark igniter mounted on the inner front
panel of the controls compartment of the heater.
4.
Pilot Generator (Thermopile) - The pilot
generator is a device, that when heated by the
flame of the pilot, generates a small electrical
voltage of approximately 750 millivolts. The
voltage is placed across the temperature controller and safety circuit of the heater. If this current
is broken at any time, the gas valve is immediately shut off and the heater stops firing. This
voltage is also used to activate the gas valve's
pilot coil which allows gas to flow to the pilot
after the gas valve knob is released.
10.4 Electrical Troubleshooting
This section describes procedures for checking
the pilot generator and control components of the
heater one at a time and in the order they appear in the
control circuit.
Page 30
Note: Pump must be running during the
troubleshooting procedure.
These procedures require a voltmeter with a
minimum 0-1000 mVDC range. Figure 24 shows the
pilot generator and control circuits, and where to take
measurements. Location numbers and letters in circles
have been added, and will be referenced in the following sections.
As stated at the beginning of this manual, some
of these procedures are hazardous. Only a qualified
service technician should service the heater.
During the trouble shooting procedure, the filter
pump must be on, the pilot on the heater must be lit,
the ON/OFF switch on the heater must be in the ON
position and the control knob must be turned to the
maximum setting so that there is a call for heat. We
recommend turning the gas valve control knob to the
"PILOT" position to prevent the main burners from
firing throughout the procedure. Before starting the
procedure, be sure that the pilot has been lit for at least
2 minutes and that the pilot generator (thermopile) is
positioned correctly within the flame of the pilot.
The pilot generator also operates the pilot coil of
the gas valve, allowing gas to flow to the pilot when
the gas valve knob is released from the pilot lighting
position (see Section 7.3 "Lighting and Shutdown
Procedures"). If the pilot will not stay lit when the gas
valve knob is released, check the pilot generator
output as described in Section 10.4.2 and replace if
necessary. If the pilot generator output is sufficient,
then check the gas valve as outlined in Section 10.4.1.
10.4.1
Gas Valve
The gas valve consists of two separate internal
operating valves. The main valve supplies gas to the
main burners for heater operation. The pilot valve
supplies gas to the pilot when the pilot generator
activates the pilot coil.
If the pilot will not stay lit after following the
lighting instructions in Section 7.3, check for the
following:
• Pilot generator output
• Correct type of gas supplied
• Correct gas supply pressure
• Air in the gas line
• Pilot coil wire connections clean and tight
If the pilot will not stay lit after checking the
items listed above, the pilot coil may be causing the
fault. Replace the gas valve.
If the main burners will not light after following
the lighting instructions in Section 7.3, check the
voltage reading between the PP terminal on the gas
valve (test point 1) and the TH terminal on the gas
valve (test point 17). If the meter shows less than
220mVDC then there is a problem with the pilot
generator, the sensors in the safety loop or the control
panel. Follow the trouble shooting procedure as
outlined in sections 10.4.2 through 10.4.7.
If the meter shows more than 220mVDC at test
point 17, then check for the following:
• Correct type of gas supplied
• Correct gas supply pressure
• Correct gas manifold pressure
• Correct orifice size
• Air in the gas line
If the main burners will not stay lit after checking the items listed above, the gas valve may be
causing the fault. Replace the gas valve.
10.4.2 Pilot Generator
The pilot generator generates a 700-750mVDC
signal when heated by the pilot flame. When the pilot
generator is connected to the heater's control components, there will be some voltage drop in the circuit so
that the measured voltage will be less than 750mVDC.
But the measured voltage should never be below
500mVDC when the ON/OFF switch is in the "OFF"
position or 220mVDC when the ON/OFF switch is in
the "ON" position.
With the pilot generator connected to the gas
valve and the ON/OFF switch in the OFF position,
place the red lead of the voltmeter on the PP terminal
(test point 1) of the gas valve. Place the black lead of
the meter on the PP/TH terminal (test point 2) of the
gas valve. The meter should show a minimum of
500mVDC. If the meter show less than 500mV, check
for partial shorts, loose or corroded connections or
partially broken wires between the pilot generator and
the gas valve.
If the wires and connections are sound, check the
pilot generator output. Disconnect the pilot generator
from the gas valve. The pilot will go out. Light the
pilot while pressing down on the gas valve control
knob. Continue holding the knob for at least one
minute. Immediately measure the voltage between the
two wires of the pilot generator. If the meter does not
show at least 700mV, replace the pilot generator.
10.4.3
Fusible Link
Check the voltage going to the safety circuit. Be
sure that the pilot generator is correctly wired to the
gas valve, the pilot is light and the control knob on the
gas valve is in the "PILOT" position. Leave the red
voltmeter lead in place at test point 1. Touch the
black lead of the meter to the terminal of the fusible
link where the white wire from the gas valve is
connected (test point 3).
If no voltage is detected at test point 3, the wire
between the gas valve and the fusible link is broken.
Replace the wire.
If there is a minimum of 220mV at test point 3,
move the black meter lead to the other terminal of the
fusible link (test point 4).
If no voltage is detected at test point 4, the
fusible link has failed. This indicates higher than
normal temperatures in the component compartment
(vestibule). Normal component compartment temperature is well below 300oF. The fusible link is designed
to fail at temperatures above 305°F. Excessive temperature might be due to a blocked flue or heat exchanger. Clean the heat exchanger and clear the flue
and vent of any restrictions. Sometimes the fusible
link fails due to flame roll-out. Flame roll-out may be
caused by delayed ignition or downdrafting in windy
areas. Thoroughly investigate the causes for flame
roll-out and correct the problem when replacing the
fusible link.
10.4.4
Fireman Switch and External
Interlocks
Check the voltage going to the external device.
Touch the black lead of the meter to the fireman
switch terminal strip where the white wire from the
fusible link is connected (test point 5). The meter
should read at least 220mV. If the voltage is less than
220mV, there may be a bad connection or wire
between the fusible link and the terminal strip. The
wire may need to be replaced. If voltage of 220mV or
more is detected at test point 5, move the black lead of
the meter to the fireman switch terminal strip connection where the white wire from the high limit is
connected (test point 6). The meter should read at least
220mV. If there is no voltage, the time clock switch or
other external interlock may be mis-adjusted, misconnected or defective. Correct this external problem.
10.4.5
Limit Switches
Since the limit switches are not easily accessible,
you can check the voltage going into the component
after the limit switches in the circuit. If voltage is
detected there, then the limit switches are closed and
are operational.
Check the voltage going to the water pressure
switch. Leave the red voltmeter lead in place at test
point 1. Touch the black lead of the meter to the
terminal of the water pressure switch where the white
wire is connected (test point 11).
If the voltage is less than 220mV, there may be a
bad connection, a partial short or a faulty sensor. If
there is no voltage, one of the limit switches is open.
This is normally due to excessive water temperature,
which should be thoroughly investigated before
Page 31
replacement of limit switches. Excessive water
temperature may be caused by low water flow. Water
flow deficiency may be due to obvious problems such
as a defective pump or blocked water filter. Alternatively, excessive water temperature may be due to
over-firing, or to a problem with the water piping or
the heater's internal bypass control. Over-firing might
be a result of an incorrect gas orifice or supply of
propane gas to a heater intended for natural gas.
If there are no such fundamental problems,
identify which of the switches is open. Limit switch
access is through the limit switch cover on the inlet/
outlet header. Remove the cover and retainer bracket
from the high limit switches and remove the limit
switches from the wells. Move the black lead of the
meter to the terminal on the 150°F limit switch (test
point 7) that is connected to the fireman switch
terminal block. Less than 220mV at this point means
that the wire between the terminal block and the limit
switch has a poor or broken connection or a partial
short. Replace the wire assembly. If at least 220mV is
detected at test point 7, then move the black lead of
the meter to the other terminal of the 150°F limit
switch (test point 8). Low or no voltage here means
that the limit is open and must be replaced.
If 220mV or more is detected at test point 8,
move the black lead of the meter to the terminal on the
135°F limit switch (test point 9) that is connected to
the 150°F limit switch. Less than 220mV at this point
means that the wire between the two limit switches has
a poor or broken connection or a partial short. Replace
the wire assembly. If at least 220mV is detected at test
point 9, then move the black lead of the meter to the
other terminal of the 135°F limit switch (test point
10). Low or no voltage here means that the limit is
open and must be replaced. If voltage is detected at
test point 10, move the black lead of the meter to the
terminal of the water pressure switch where the white
wire from the high limits is connected (test point 11).
Less than 220mV at this point indicates that the wire
connecting the high limits to the water pressure switch
is faulty or poorly connected. Correct the problem or
replace the wire.
Note: The limit switches have different trip
points, and it is important that replacements
are correct. The 150°F switch has a red dot on
the top of the brass fitting, and must be
installed in the lower (horizontal) well in the
header. The 135°F switch has no dot and must
be installed in the upper (vertical) well in the
header.
Page 32
10.4.6
Water Pressure Switch
If the meter shows at least a 220mV signal at test
point 11, move the black lead of the meter to the other
terminal on the water pressure switch (test point 12).
If there is no voltage, the pressure switch contacts
are open. This is almost always due to a water flow
deficiency, the most common one being a blocked
water filter or defective pump. However, sometimes it
is due to blockage of the copper siphon loop tube or
mis-adjustment of the switch. Investigate thoroughly,
referring to Section 7.5 on “Water Pressure Switch
Adjustment”. If there is no problem with the pool
system or pressure switch adjustment, replace the
pressure switch.
10.4.7
Temperature Control Circuit
The temperature control circuit consists of four
major components which must all be working correctly for the signal to be transmitted to the gas valve.
The four components are the ON/OFF toggle switch,
the variable temperature control (potentiometer), the
temperature sensor (thermistor) and the temperature
control board. Use the following procedure to check
each component for functionality.
Check the temperature control as a complete
circuit before checking each component individually.
With the red lead of the meter still at test point 1,
place the black lead of the meter on the TH terminal of
the temperature control circuit board (test point 16). If
the meter shows more than 220mV at the pressure
switch (test point 12) but not at test point 16, then one
of the components of the temperature control circuit is
faulty. Proceed with the following sections to test the
components.
10.4.7.1 ON/OFF Toggle Switch
Remove the temperature control panel from the
bezel on the front of the heater to gain access to the
switch. Be sure that the toggle switch is in the "ON"
position. Place the black lead of the meter on the
toggle switch terminal (test point 13) that is connected
to the pressure switch. Less than 220mV at this point
indicates that there is a problem with the black wire
that connects the pressure switch to the toggle switch.
If at least 220mV is detected at test point 13, move the
black meter lead to the other terminal on the toggle
switch (test point 14). A reading of less than 220mV
here indicates a faulty switch. If the reading is more
than 500mV, turn the switch "OFF" and then "ON"
again to be sure that the internal contacts are working
correctly. The volt meter reading should drop to zero
when the switch is "OFF" and return to at least 220mV
when the switch is placed back in the "ON" position.
10.4.7.2 Variable Temperature Control
The variable temperature control is a 0-10,000
ohm variable resistor. Set your ohmmeter to the 0-20K
range. Remove the temperature control wires from
the control circuit board. Place one lead of the meter
on each of the wires (test points 18 & 19). With the
control set to MIN the meter should read near 10,000
ohms. Now turn the control to the MAX position. The
meter should read close to zero. If the meter shows an
open circuit, or readings outside of the range stated
above, replace the controller. If the control is working
correctly, reconnect the wires to the circuit board.
10.4.7.3 Temperature Sensor
The temperature sensor is a 0-20,000 ohm
thermistor. Set your ohmmeter to the 0-20K range.
The meter readings will depend on the temperature of
the water in the header. See the chart below for
approximate readings at various temperatures.
To test the temperature sensor, circulate water
through the heater for 5 minutes. Remove the temperature sensor wires from the temperature control board.
Place one lead of the meter on each wire of the
temperature sensor (test points 20 & 21). Record the
reading. Measure and record the water temperature of

temperature in the chart that is closest to your temperature reading of the pool water. Compare your
ohmmeter reading to the resistance number in the
chart. Remember that this is an approximate reading
and numbers may vary. If your reading is close to the
numbers indicated in the chart then the temperature
sensor is working correctly. Reconnect the wires to the
circuit board. If your reading is vastly different or
outside of the ranges shown the temperature sensor
should be replaced.
10.4.7.4 Temperature Control Circuit
Board
With the red lead of the meter still at test point 1,
place the black lead of the meter on the TH/PP terminal of the temperature control circuit board (test point
15). If there is more than 220mVDC at this point but
not at the TH terminal of the temperature control
circuit board (test point 16) as tested in section 10.4.7,
then the control circuit board is faulty. Replace the
board.
